[mapserver-users] The browser can't display the rendered image

Wed Nov 19 12:26:02 PST 2008

Your image link in http is a direct link to your hard drive.  I do not think your web server likes this.  The ms_tmp directory has to be readable by apache, and therefore, it must be in the apache htdocs path, or specified in the httpd.conf file to be readable.

HTH,

Subject: [mapserver-users] The browser can't display the rendered image

Hello,

I still have got a problem. I ve tested my mapfiles (with quickmap.php) and they work fine, but the problem is the same. My php/mapscript code created the map image and saved it to "/ms_tmp/" but the browser couldn't display it (I got a broken img). I enclose the php/mapscript file, the mapfile and the page source.Thx for ur help and patience.

PHP/MAPSCRIPT FILE:

<?php
define( "MAPFILE", "/ms4w/apps/raster/raster.map" );
define( "MODULE", "php_mapscript.dll" );
if(!extension_loaded("mapscript")) dl(MODULE);
$oMap = ms_newMapObj( MAPFILE );
//draw
$oImage = $oMap->draw();
//output map
$url = $oImage->saveWebImage();
?>
<HTML>
   <HEAD>
      <TITLE>Example 1: Displaying a map</TITLE>
  </HEAD>
  <BODY>
      <IMG SRC="<?php echo $url; ?>">
  </BODY>
</HTML>

MAPFILE (I created it with qgis):

MAP
  NAME world_raster
  SIZE 600 600
  UNITS dd

END

Page source (after I ran the code the html part saw the link to the image but didn't display it.):

</HEAD>
<BODY>
<IMG SRC="c:/ms4w/tmp/ms_tmp/4923f091_c84_0.jpeg">
